FROM THE LAB TO THE FIELD - DEMONSTRATING BIOAUGMENTATION IN SITU TO ENHANCE ANAEROBIC BENZENE BIODEGRADATION

A methanogenic benzene enrichment culture (DGG-B) developed at the University of Toronto transforms benzene under either methanogenic or sulfate-reducing conditions. The first field application of the DGG-B bioaugmentation culture is planned for summer 2019 at a site in Saskatchewan, with several other sites to follow. The presentation includes results from treatability studies, which aided in the field pilot test design. One field pilot test will include three injection points, two of which will receive up to 10 L of DGG-B culture. Killed culture will be applied at the third to serve as a control and determine if dead cells promote any degradation. These first field projects will establish clear guidelines and approaches for using these new bioaugmentation cultures. https://www.esaa.org/wp-content/uploads/2019/10/19-Dworatzek.pdf.
